Crafted by Pella, Certified by ENERGY STAR® ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy to help Americans shield the environment through energy efficient products and practices. Since ENERGY STAR focuses on saving energy, you’ll likely also save on your energy costs. All Pella glass options meet or exceed ENERGY STAR certification in all 50 states. What does this mean for you? Not only might you see lower heating and cooling costs, you’ll also help support the environment. Moreover, you’ll add to your home’s comfort since our ENERGY STAR certified glass blocks a large percentage of the sun’s ultraviolet rays. That means virtually no fading for your window treatments, carpet, furniture and walls. Look for the ENERGY STAR logo on our products as you peruse through our site or Danville Showroom. You’ll find it located on the product’s NFRC label. Some of our products significantly exceed U.S. ENERGY STAR guidelines. Contact your Danville Showroom to learn more. Schedule Now!
